Climbing roses, according to Clemson University Extension, are a fast-growing rose, sending out canes that require training over fences or trellises. Some climbing roses will grow quite large, reaching a height of 50 feet or more; however, most climbing roses will reach a height of 8 to 15 feet tall. Climbing roses are also long living, some varieties lasting for 50 years. Proper care ensures your climbing roses will reach their full growing potential.
Find a site to plant your climbing roses that has a rich, loamy soil that drains well, and mix organic materials into the soil before planting, says Colorado State University.
Train climbing roses as they grow, recommends Ohio State University, by guiding vines vertically along a trellis or pole. Tie the shoots to the support system using soft cloth.
Apply a 2- to 3-inch layer of grass clippings, wood chips or hay to retain moisture. This keeps moisture in the soil.
Fertilize your climbing rose bush with 3 lbs. of nitrogen per 1,000 square feet per year, spreading the amount over three different applications throughout the year, says Ohio State University. Apply in early spring, after the first bloom, and before the end of August.
Water the climbing rose bush so that the soil is moist to a depth of 2 to 3 inches, says Colorado State University. Probe in the soil using a shovel to ensure the water is reaching the correct depth. Water with overhead sprinkling or a hose to prevent damage to flowers.
Prune dead or broken wood from the climbing rose as it appears. Climbing roses do not require further pruning, according to Colorado State University.
Form a mound of organic material around the crown of the climbing rose bush before winter to prevent frost damage. Wood chips or pine needles will protect the plant.
